1  Using Arduino / Project Guidance / Re: How to get MCP3002 to work with arduino? on: November 04, 2012, 06:04:50 am
Sorry, I did forgot to post the links...

Camera: http://www.hobbyking.com/hobbyking/store/__26833__Micro_Camera_with_LED_Lamp_420TVL.html
MCP3002: https://www.sparkfun.com/products/8636

I want it to make the analog video signal from the camera digital and transfer it wirelessly trough a bluetooth or rf module to my computer. The ADC that is intergrated in the arduino is not good enough. I have no sample pictures of it yet.

But since the ADC I got uses SPI, do I have to send the video signal trough the arduino then? Or can I send it directly to a bluetooth/rf module?

And how should I connect the ADC to the arduino? Any test codes?

Hello,

In my arduino project I have added a camera, an analog to digital converter (MCP3002) and are using an Arduino pro 5v. I can not get the camera to work with this ic chip. Does anyone have some code to test with? Or can anyone help me to get it to work?
3  Using Arduino / Microcontrollers / Re: Arduino Leonardo, product page says 20 I/O pins? on: October 22, 2012, 09:11:48 am
Aha, I see. But what about the Uno? It can also use the analog as digital pins. I have done it some times with no problem at all. So why does it not stand on the uno 20 digital pins?

Hello,

I just got an arduino Leonardo, and on the product page, it says it has 20 digital I/O pins and 12 analog. I can only see 14 digital and 6 analog. Are they missing or something?
I know I can use the analog pins as digital pins, so if I use all as digital, i get 20. But on the Uno, I can do the same, and on that product page, it only says 14.

So is it a typo, or is it something else with these boards?

Hi, sorry for my late reply.

When a 9V battery is connected, I mesuere 3,78V between +5V and GND pins.

Where is the ICSP header on the mini?

I think your usb hub is the problem. My last hub just splittes the cables to both ports, so they had the same tx/rx..

Hi,

I got a problem with my arduino mini 04. When I power the board with batteries trough the +9v pin and gnd, the setup or loop does not run. It does not matter how many amps or what voltage I give it there. If I power it trough a voltage regulator to the +5v pin, it works fine.

I have a led connected to pin 13, and that blinks on startup, but nothing more. I have tried different codes to test, but no result, still a problem.

So, I think it is an hardware problem, maybe a voltage regulator on the board or something, but I really don't know yet. So I hope you guys can help me out. smiley

Regards,
The Crusher
9  Using Arduino / Installation & Troubleshooting / Re: Arduino mini, leds blinks when it shouldnt whith battery power on: August 05, 2012, 08:38:01 am
Any help?
10  Using Arduino / Installation & Troubleshooting / Re: Arduino mini, leds blinks when it shouldnt whith battery power on: July 24, 2012, 03:08:09 pm
It is still not working. Have tried different test codes, like the blink example, and the test code as posted above in the thread( It is a modifyed blink example...)

I have tried with and without the radio module, the only difference was the led did not blink as it did whit it connected. It is hard to explain how it did blink, but I can try. When the led should be on, and not blink, it looks like it blinks with a 10ms delay between the blinks, and it is almoust not visible, but the brightnes is oufcorse weaker... But whit the radio module removed, it did work properly at startup, but the setup() (witch sets pin13 HIGH) does not start, and since there is no setup() starting, no loop() either.

Can someone help me?

Have you choosed the rigth serial port and right board in the Arduino software?

Any Ideas?

If you read the thread you find the info you need, like hardware and code..
13  Using Arduino / Installation & Troubleshooting / Re: Arduino mini, leds blinks when it shouldnt whith battery power on: July 09, 2012, 06:32:10 pm
As I wrote, the hardware that has been connected is the radio module I linked to earlier. It only takes 48mA max on Tx(or Rx, dont remeber...)

I removed it, and using the same code as posted above. The only thing, is that when the radio module is not connected, I can not switch it off or on, but in the setup() it sets 13 high, so it lights up when it is starting.

the 9v battery is a small rectangle type, yes. I have tried different power sources. The battery was on 200mA, but I have also tried to power it with a more powerfull 9V battery on 2000mA. No difference, since the regulator does not let so much power go trough. But why does not the loop run?

I have also tried to power up the radio module with a separate power supply. Still no loop running.. I can try to upload a different code, but it should work with this one too...

Pin13 is connected to the led, nothing else.

It seems like the setup() and loop() does not run. But only when I supply power trough the 9V pin. If I use a battery on 5V and supply it trough the 5V pin, it works fine. But any voltage from 5-9V on the 9V pin, then it does not work.

The LED blinks when it get data on RX from the radio module. But in the setup, it sets it high, so it should turn on. And no, it does not.

No, the led is not turned arround. It blinks at startup.
